Matthias J. Sax resolved KAFKA-6910.
------------------------------------
Resolution: Duplicate
> Ability to specify a default state store type or factory
> --------------------------------------------------------
>
> Key: KAFKA-6910
> URL: https://issues.apache.org/jira/browse/KAFKA-6910
> Project: Kafka
> Issue Type: New Feature
> Components: streams
> Affects Versions: 1.1.0, 1.1.1
> Reporter: Antony Stubbs
> Priority: Major
>
> For large projects, it's a huge pain and not really practically at all to use
> a custom state store everywhere just to use in memory or avoid rocksdb, for
> example for running a test suite on windows.
> It would be great to be able to set a global config for KS so that it uses a
> different state store implementation everywhere.
> Blocked by KAFKA-4730 - Streams does not have an in-memory windowed store.
> Also blocked by not having an in-memory session store implementation. A
> version simple in memory window and session store that's not suitable for
> production would still be very useful for running test suites.
